中文摘要 | bagdf(5):yb(3+)/er(3+) colloidal nanoparticles (nps) with tunable average particle diameters from 3 to 10 nm in different solvents were first prepared by thermal decomposition method. x-ray diffraction (xrd), transmission electron microscopy (tem) and upconversion (uc) luminescence spectra were used to characterize the resulting samples. after coating the active shell (containing yb(3+)) around the bagdf(5):yb(3+)/er(3+) nps, not only their morphology and monodisperse properties were well maintained but also the relative uc luminescence intensity was enhanced remarkably. in contrast to the pure bagdf(5):yb(3+)/er(3+) core, the luminescence intensity of the active-shell coated nps can be enhanced several hundred times. unexpectedly, the luminescence intensity of the active-core/active-shell nps was about four times as high as that of beta-nayf(4):yb(3+)/er(3+) nps under the same doping concentration and measurement conditions. moreover, the luminescence colors of the active-core/active-shell nps can be tuned from green to yellow by multilayer active-shell coating under 980 nm laser excitation. |
